Lobsters don't have vocal cords, and even if in agony, they cannot vocalise. The high pitched sound made by an overheating lobster is caused by expanding air rushing out of small holes in lobsters' bodies, like a whistle being blown. A dead lobster will “scream” just as loudly as if it was living.
Most likely, yes, say animal welfare advocates. Lobsters belong to a family of animals known as decapod crustaceans that also includes crabs, prawns, and crayfish. Scientists have observed immediate and long-term changes in behavior in decapods that show that they respond to stress and learn from painful experiences.
Lobsters and other shellfish have harmful bacteria naturally present in their flesh. Once the lobster is dead, these bacteria can rapidly multiply and release toxins that may not be destroyed by cooking. You therefore minimise the chance of food poisoning by cooking the lobster alive.
If a lobster dies, you only have a few hours before these bacteria show up to the party. And once they're in, it's nearly impossible to get rid of them. Even cooking the lobster meat won't kill all of the bacteria. So it's safer to just keep the animal alive right up until you serve it.
What about Australia? Switzerland is not the first place to ban boiling live lobsters; it's already illegal in New Zealand and in the Italian city of Reggio Emilia. In several Australian states, including New South Wales, fish and crustaceans are included in animal cruelty laws.
Scientists have found that it can take lobsters between 35 – 45 seconds to die when plunged into a pot of boiling water — and if they are dismembered their nervous system can still function for up to an hour.
Contrary to claims made by seafood sellers, lobsters do feel pain, and they suffer immensely when they are cut, broiled, or boiled alive. Most scientists agree that a lobster's nervous system is quite sophisticated.
Head First into Boiling Water
Hold the lobster around the middle to avoid those claws and put it head first into the water. It will die quickly. Boiling water is also the best way to cook the lobster so you can leave it in there and carry on the cooking process.
Do Lobsters Feel Pain When Cut In Half? Again, all the evidence shows that they do. And considering their nervous systems cannot go into shock, they are likely to feel this pain for up to an hour after being cut in half.
To break down a lobster, you'll want to shuck the claws, then the tail and head, then the legs. Avoid eating the shells, cartilage, and tail vein, as they're not edible and/or tasty.
Researcher Michael Kuba says that lobsters are “quite amazingly smart animals.” Like dolphins and many other animals, lobsters use complicated signals to explore their surroundings and establish social relationships.
While mammals and birds possess the prerequisite neural architecture for phenomenal consciousness, it is concluded that fish lack these essential characteristics and hence do not feel pain.
A researcher in animal behaviour says it's 'very likely' lobsters and other crustaceans can feel pain when they are boiled alive. A researcher in animal behaviour recommends people kill their lobsters before cooking them, after extensive research suggests crustaceans can feel pain.
One of their claws can exert pressure of up to 100 pounds per square inch. So they may not feel pain, but they can cause some serious pain.
“As it turns out, lobsters don't mate for life,” explained Mr. Wheir, a video editor in New York. Actually, male lobsters in particular are rather promiscuous. “Lobsters do have a monogamous bond, but it only lasts for two weeks,” said Trevor Corson, the author of “The Secret Life of Lobsters” (HarperCollins, 2004).
Freezing Live Lobsters: Just Don't Do It
Safety aside, freezing and thawing lobster prior to cooking it will lead to enzymes leaching into the meat, resulting in a mushy, unappetizing texture.
Plunging them into boiling water, freezing them or 'drowning' them in fresh water are not humane.
Lobsters don't have vocal cords, and even if in agony, they cannot vocalise. The high pitched sound made by an overheating lobster is caused by expanding air rushing out of small holes in lobsters' bodies, like a whistle being blown. A dead lobster will “scream” just as loudly as if it was living.
It's not necessary, but if you'd like to kill the lobster before cooking it, do so by driving a knife into the center of its head and pushing down to split it open.
Cooking a lobster for too long will make it tough and rubbery. Lobster meat should be white, opaque, not translucent.
Lobsters can live up to 48 hours out of circulating salt water if they are properly refrigerated. Lobsters don't need to be jumping out of the box to be fresh and good eating. They should, however, be checked upon arrival. If they are not moving, it is best to cook them immediately.
Many people have heard that boiling crustaceans alive is a painful and inhumane way to kill a crab or lobster and this is backed up by many convincing studies as well as physical evidence such as animals dropping their limbs and writhing around before dying.
